Water was sacred, for Lord Tulkas resided there in the springs and in the very ocean itself. He was the Lord of the Waters, and the one element that Morgoth dare not cross, and no evil spirit dare wade into. The fords were places of refuge, so that when all was lost one could jump into the middle of the springs and be protected from all sides. It was a blessing to touch the water now, and infuse it with the grace of his elven soul. For those able to see Maedhros in his true form, it would appear that he shown with a bright light like the very stars above.
Ariel joined in his tune, with music of her own. His heart soared in delight and a brilliant smile flashed across his visage, lightening his features. She could sing! There were few things that elves enjoyed above all others and music was one of them. It was a lovely tune of her's that touched his ears and made them twitch forward in eager interest. Leaning closer to the water, Maedhros's low hum turned to words in Quenya, the sacred language of the Noldor. It rolled off of him with a natural grace, and joined itself with the very world around them, and through connection of his hand into the water itself. The fish, which at first had been instinctively frightened of a dangerous invasion of his hand, flocked to him in small schools.
Maedhros looked at them pleasantly, and gestured with his wounded arm for her to touch the water. "Feel the life of them," he said quietly, "and listen for their voices. It is very faint, but they will wake."
